Automotive sheet metal is a technical means of automobile repair. In this respect, automotive sheet metal is equal to the repair of automotive sheet metal, which means that the car body should be repaired after the collision, that is, all the work except the anti-corrosion and decorative spraying of the car body.

Such as body damage analysis, body measurement, body sheet metal shaping, stretching correction, stress relief welding, body accessories assembly adjustment, etc.

material requirements

1, the sheet metal material must have good plasticity. Must have the ability to produce permanent deformation under the action of external force without being destroyed. For cold-worked parts, good cold plasticity is required, such as stamping parts of automobile parts; For hot working parts, good thermoplasticity is required, such as hot forgings, spring steel plates, hot rivets, etc.

2. Good weldability. Many automobile sheet metal parts are welded together by spot welding, oxygen welding, arc welding or gas shielded welding, so it is required that the sheet metal parts must have good welding performance. This is especially important in automobile maintenance and repair. Materials with good weldability have high welding strength and low cracking tendency.
